PURPOSE: Currently, almost all adrenal venous sampling (AVS) procedures are performed by femoral vein access. The purpose of this study was to establish the technique of AVS via an antecubital approach and evaluate its safety and feasibility. MATERIALS AND METHODS: From January 2012 to June 2015, 194 consecutive patients diagnosed as primary aldosteronism underwent AVS via an antecubital approach without ACTH simulation. Catheters used for bilateral adrenal cannulations were recorded...

BACKGROUND AND AIM: Primary aldosteronism (PA) is one of the most common causes of secondary hypertension. Adrenal vein sampling (AVS) remains a "gold standard" procedure in differentiation between unilateral (adenoma) and bilateral (hyperplasia) disease. We present our single-center experience in establishing and implementation of the AVS procedure. METHODS: All patients had primary aldosteronism confirmed in salt-infusion test. Adrenal vein sampling was performed sequentially during a continuous intravenous infusion of cosyntropin and was preceded by multislice contrast-enhanced computed tomography (CT) examination of adrenal glands performed few weeks before AVS in majority of patients...

In this retrospective study, we aimed to examine the effect of applying Dyna computed tomography (CT) on the success rate of adrenal venous sampling (AVS) without adrenocorticotropic hormone stimulation. A total of 100 consecutive patients with primary aldosteronism who underwent AVS between May 2012 and July 2015 were enrolled. In all the cases, Dyna CT was used in AVS to validate catheter position in the right adrenal vein. A selectivity index (cortisoladrenal vein /cortisolinferior vena cava) of ≥2.0 of both adrenal veins were required for successful AVS...

OBJECTIVE: Difficulty to recognize or canulate the right adrenal vein is the most frequent cause of adrenal venous sampling (AVS) failure. We aimed to assess multinomial regression modeling (MRM) of peripheral and left adrenal vein samplings to detect lateralization of aldosterone secretion when the right AVS is missing. METHODS: Simultaneous bilateral AVS samplings were performed before (basal) and after intravenous cosyntropin injection in 188 consecutive patients between December 1989 and September 2015...

BACKGROUND: For radiologists, the venous drainage of adrenal glands is a key to the technique of selective adrenal venous sampling. For endocrine surgeons, it is key to adrenalectomy for carcinoma and pheochromocytoma. This study aims to demonstrate direct anastomosis between the left adrenal vein, the diaphragmatic circulation and the azygos system. Anatomical textbooks only offer very little information concerning the left adrenal vein (LAV) and its potential anastomosis with the reno-lumbo-azygo trunk (RLAT) and the diaphragmatic circulation...

OBJECTIVE: Many investigators believe that basal adrenal venous sampling (AVS) should be done simultaneously, whereas others opt for sequential AVS for simplicity and reduced cost. This study aimed to evaluate the concordance of sequential and simultaneous AVS methods. DESIGN AND METHODS: Between 1989 and 2015, bilateral simultaneous sets of basal AVS were obtained twice within 5 min, in 188 consecutive patients (59 women and 129 men; mean age: 53.4 years). Selectivity was defined by adrenal-to-peripheral cortisol ratio ≥2, and lateralization was defined as an adrenal aldosterone-to-cortisol ratio ≥2, the contralateral side...

BACKGROUND: Oxidative stress in primary aldosteronism (PA) is thought to worsen aldosterone-induced damage by activating proinflammatory processes. Therefore, we investigated whether inflammatory markers associated with oxidative stress is increased with negative impacts on heart function as evaluated by echocardiography in patients with PA. METHODS: Thirty-two subjects (mean age, 50.3±11.0 years; 14 males, 18 females) whose aldosterone-renin ratio was more than 30 among patients who visited Severance Hospital since 2010 were enrolled...

INTRODUCTION: During adrenal venous sampling (AVS) procedure, radiologists administer a contrast agent via the catheter to visualize the proper catheter position. MATERIALS AND METHODS: A patient with primary aldosteronism diagnostic-hypothesis was admitted for AVS. A venogram was performed to
confirm the catheter's position with 2mL of Iopamidol 300 mg/mL. Samples were collected with syringe connected to a hydrophilic coated catheter by low-pressure aspiration from each of the four collection sites: inferior vena cava in the suprarenal portion, inferior vena cava in the infrarenal portion, left adrenal vein, and right adrenal vein; then immediately transferred from syringe to tubes with gel separator...

Hypokalaemia as a typical feature of primary aldosteronism (PA) is associated with muscle weakness and could contribute to lower cardiopulmonary fitness. The aim of this study was to describe cardiopulmonary fitness and exercise blood pressure and their determinants during a symptom-limited exercise stress test in patients with PA. We performed a cross-sectional study of patients with confirmed PA who were included before adrenal vein sampling on whom a symptom-limited exercise stress test with expired gas analysis was performed...

Primary aldosteronism (PA) is an important and commonly unrecognized cause of secondary hypertension. Idiopathic hyperaldosteronism and aldosterone-producing adenomas account for more than 95% of PA and are characterized, respectively, by bilateral or unilateral involvement of the adrenal glands. When there is suspicion for the presence of PA, a plasma aldosterone to renin ratio should be obtained initially. Localization to determine adrenal gland involvement is done by imaging, with computerized tomography or magnetic resonance imaging...

OBJECTIVE: Adrenal vein sampling (AVS) is vital for determining treatment options for primary aldosteronism (PA), but is a difficult procedure. Adrenocorticotropic hormone (ACTH) infusion or bolus has been reported to improve AVS success rates by increasing cortisol secretion, but effects on aldosterone and thus lateralisation are controversial. We therefore aimed to determine the effects of ACTH on AVS in regard to success rates and lateralization. DESIGN AND METHOD: AVS was performed in the morning after overnight recumbency in patients with PA confirmed by fludrocortisone suppression testing...

OBJECTIVE: Adrenal venous sampling (AVS) is recommended by clinical guidelines to distinguish surgically curable types of primary aldosteronism, but remains widespread underused mainly due to difficulty in successful sampling. When considering that the right adrenal vein is angled caudally, AVS through upper extremity approach may be more appropriate. The purpose of this study was to establish the technique ofAVS via median cubital vein (MCV), and evaluate its safety and feasibility. DESIGN AND METHOD: From January 2012 to June 2015, 194 consecutive patients diagnosed as primary aldosteronism underwent AVS via MCV at the Fuwai Hospital...

Primary aldosteronism (PA) involves more than 11% of patients referred to specialized hypertension centers and, therefore, is much more common than commonly held. Moreover, it causes a damage to the heart, blood vessels and kidneys, which translates into a high rate of cardiovascular events, in excess to the degree of blood pressure raise. Along with the notion that a timely diagnosis entails a fundamental step for the choice of an appropriate therapy, which can correct the arterial hypertension and the hypokalemia, this justifies efforts to search for PA in the majority of the patients with hypertension...

PURPOSE: To evaluate the importance of selecting an appropriate catheter shape for the right adrenal vein (RAV) anatomy on CT to the success of right adrenal venous sampling (RAVS) by elucidating the interactions of anatomical factors with catheter shape. MATERIALS AND METHODS: 130 patients with enhanced CT underwent RAVS using two catheters: catheter 1 was planar and catheter 2 was a three-dimensional shape. The following anatomical factors on CT were evaluated in each patient: presence of a right adrenal tumor, presence of a common trunk with an accessory right hepatic vein, diameter of the RAV, short and long diameters of the IVC, ratio of the long to the short diameter of IVC, and the transverse, modified transverse, and vertical angles of the RAV...
